Error: Does not exist in current context C#

Hey guys, I have an issue with C# I am trying to set a detailsview with dataset info like:

DetailsView1.DataSource = ds123;
DetailsView1.DataBind();

It is from inside a Gridview SelectedIndexChanged event handler, but it is giving me an error message "DetailsView1 does not exist in current context.

How do I fix this?

Check where you defined your DetailsView1 If it is defined in a procedure then it will not be accessable outside the procedure where it resides.

Define your vars at the top of the class to make them available to all procedures within a class.

Hey Datamiser, the detailsview1 is defined in an .ASPX page called default2.aspx in the markup. The c sharp code is sitting in a page called Default2.aspx.cs inside the function protected void View1_SelectedIndexChanged for a grid view, how would I declare detailsview1 so that I can use it inside here?

using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Data;
using System.Data.SqlClient;


public partial class Default2 : System.Web.UI.Page
{

If you want the object to be available to the entire class then you define it at the top of the class after the initial {

I got it to recognize the detailsview by declaring:

protected global::System.Web.UI.WebControls.DetailsView DetailsViewBase;

but now it says this details view is NULL, how do I assign it to what is on the webpage?

I'm not sure what you mean but with the detailsview you can select a data source via the "Details View Tasks", choose a new data source type, choose data connection then configure the select statement.

Hey Nightwalker, no, that's not what I need for the detailsview assignment. Excuse me for being a bit new with C#.net. Here's what I need, I just need to make a manual assignment to a details view object on a .NET webpage via C# code.

For example, take the string "XYZ" that you create in a string variable in C#, and then assign that to a field called "Zipper" on a details view called DetailsView1 sitting on a webpage called Default.aspx within a selected index changed from gridview, can you show me how to do that in C# code?

Thanks
